Arizona Obituary Records
Arizona has a massive retiree population, which means they often have more obituaries published every year than almost any other state. Luckily, they are on the forefront of technology when it comes to putting together easy to access databases that make finding the listing you are searching for easy.
The Mesa Arizona Regional Family History Center has a massive database that you can search to find listings from all over the state, while Maricopa County has their own listings, as well, through the West Valley Genealogical Society. The Sharlot Hall Museum in Prescott also has an Arizona obituary records index that you can access, as well. Finally, the Scottsdale Public Library has a database you can search that contains all of the listings published in the local Scottsdale Tribune newspaper from the last few years.
Since there are such a large number of requests for Arizona obituaries, more and more small town newspapers are putting their listings online. Check to see what the local paper in the area you are searching and check with them first. If that search comes up dry, one of the databases listed above will likely have what you are looking for.
